Abstract

An arrangement includes two bracket parts, each bracket part includes a vertical branch and a horizontal branch attached by two fastening points. Each fastening point includes a longitudinal opening in each horizontal branch and a first fastening member passing vertically through the two longitudinal openings into a nest supported on a horizontal branch. A second fastening member extends horizontally into the nest and is operatively connected within the nest to the first fastening member via a power transmission. Rotation of the second fastening member generates a pressure joint between the two horizontal branches in the fastening point.
